Agreed! I really like the lighting, background blur and overall look of these photos! For the 2nd & 3rd photos, I would probably have composed the photo with the dog a little more distinctly on a third, instead of kind of hovering between the right third and the center. I just feel like it would make the photo feel a little more spacious and like there’s intention in the amount of space.
That being said, I realize that might just leave a lot of empty space (which could still be nice, especially if you’re using these photos in a design), so I might look for ways to include something in the background compositionally, like if there was a tree or some other element that could sort of act as a background framing element.
The only other thing that comes to mind is to look for ways to include foreground blur. I LOVE doing this when I can. Sometimes it’s just not possible, but it can add such depth to the photo when used well.
Again, really lovely photos!
